Okay so for some reason when I'm having sex, doesn't matter with who. It could be the most unattractive to the sexiest, a client or my SO.... I think about Cornish Game Hens. I have no idea why, I mean I don't think about having sex with it, I just think of eating one. I think it's a bit odd. Maybe a phase that some providers go through. Yes i did have to share that, I feel there's someone out there that knows exactly what I mean....  

Tell me, when you were a young child, did you catch sight of a parent plucking a chicken by any chance?

...after sex.

I was kinda hoping for a joke, three hens go into a bar ...

Or choking a chicken?

doesn't the use of the word "hen" in the name exclude the male of the species?

NO, a quote from Wikipedia "Though the bird is called a "hen", it can be either male or female."

It's a curious association for sure. I would ask someone who has studied Neuro Linguistic Programming. That's my best guess. I don't have a consistent single "flash" like that but sometimes while I'm in action, my memory will flash to a place like New York or Rome just for a moment.

Or feeding the geese?

What I really want to know is what you're thinking of while you're actually eating a Cornish game hen. :P

when I'm having sex... the liftoff of Apollo 11 in July 1969.
